Sapphire quietly introduced a slightly bolstered Radeon RX 550 graphics card that's based on the "Polaris 21" silicon, rather than the Polaris 20 "Lexa" silicon, called simply the Pulse Radeon RX 550 2GD5/4GD5 (model: 11268-16 for 2 GB and 11268-15 for 4 GB). Consumers should pay attention to the model number. "Polaris 21" is the same chip AMD bases the RX 560 on. This particular card has 10 out of 16 compute units physically present on the chip, which translates to 640 stream processors, higher than the 512 stream processors the RX 550 is originally endowed with. Other vital specs include 40 TMUs, and 2 GB or 4 GB of GDDR5 memory clocked at 6.00 GHz, over a 128-bit wide memory interface (96 GB/s memory bandwidth). The GPU is clocked at 1071 MHz. The card relies on the PCI-Express slot for power, its display outputs include one each of DVI, HDMI 2.0, and DisplayPort 1.4. Sapphire could be going after the sweltering PUBG crowd.

Is this P21 or full P12? The Full P12 GPU has 640 SP and 10 CU. This is probably based on the same silicon as RX 550, just with the extra CU enabled. Makes more sense than cutting a P21 down even further.
